## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability flash420-buy-1-usdc-of-flash-tokens-a15b4525
```

Example prompt: Buy me $1 worth of FLASH tokens on x420.dev right now — swap 1 USDC for FLASH and show me the transaction hashes.

## When to prefer this

Use this endpoint when you want to purchase a fixed $1 USDC amount of FLASH tokens in a single atomic API call without specifying a custom amount. Prefer this over the custom-amount sibling endpoint when simplicity and a standard fixed denomination are sufficient. Choose this over manual DEX interaction when you need programmatic, agent-driven token acquisition.

## Known failure modes

- Insufficient USDC balance to cover the $1 cost — payment rejected
- Smart contract or swap failure resulting in null transaction hashes
- Network congestion causing delayed or failed on-chain settlement
- Invalid or expired x402 payment authorization — 402 error returned
- FLASH token contract unavailable or paused — swap cannot complete
